The DBH 1166 seal is a radial seal of design A 378 that mounts in housings of 47 mm diameter and 6.50 mm height. Its function is to retain lubricant inside the assembly and prevent the ingress of dust, water or particles that accelerate wear on bearings and bushings. It is a common replacement part in rotating equipment where the shaft rotates within a fixed housing. MR Accesorios Industriales sells this brand as part of its line of seals and oil seals.

This item is identified with code 1166 and corresponds to a radial seal of the DBH brand. According to the product page data, the housing has a diameter of 47 mm, the height is 6.50 mm and the design is A 378. Therefore, before ordering it, it is advisable to verify the shaft size where the lip will seat.

Radial seals of this type are used in gearboxes, pumps, electric motors, transmission shafts and continuous process equipment. They also appear in agricultural machinery, conveyors and centralized lubrication systems. In all cases, the purpose is the same: confine the oil or grease and protect the bearings from external contamination. When the seal loses elasticity or the lip wears, lubricant leakage and dirt ingress begin to appear, which shortens the service life of neighboring components.

To properly select a seal, three things must be checked: shaft diameter, housing diameter and height. Additionally, the condition of the shaft surface matters: if it has burrs, deep scratches or wear, the new lip will not seal properly even if the size is correct. During installation, lubricate the lip with the same grease or oil used in the equipment, insert it perpendicular to the shaft and avoid striking it with tools that deform the metal case. If the housing is damaged, consider repairing it or using a seal with a wear sleeve.

If code 1166 does not exactly match what you need, or if the shaft diameter of your equipment is different, an equivalent or a neighboring size within the same radial seal category can be found. For that, the most practical approach is to send us the original code, a photo of the part and the measurements taken with a caliper via WhatsApp: shaft diameter, housing diameter and height. With that data, at MR Accesorios Industriales we review alternatives and provide you with a quote.
